other schools, to facilitate teaching of modeling and drawing.

Objects such as statues, images, or the like,

produced in accordance with the present invention are many times lighter than plaster molds, are easlly capable of trans ortation in the mails without breakage, an are pre pared in such a manner as torender them non-combustible, water-proof, and. washable.

For a full understanding of the invention, reference. is to be had to the following detail description and to the accompanying drawings, in which.

Figure'l is a front view of a reproduction made in accordance with the invention, and Fig. 2 is a rear View thereof showing 'most clearly the manner of application of thereinforcing strips of asbestos. v

Throughout the following description and onthe several figures of the drawlngs similar parts are referred to by like reference characters.

Describing the invention specifically it is contemplated to practice the same. in two different ways in the making of simple and complicated m dels or reproductions. ,The

principle or process involved in carrying out the invention, is the same in both instances.

For reproducing simple art models it is contemplated to moisten several sheets of asbestos which are then pasted together by any suitable adhesive. A composite layer or with; a compound made of body of material 1 is thus constituted, and is of a pliable or flexible nature. This moistenedlayer or leather-like sheet of substance is shaped over the original model, and of which a reproduction isbeing made, suitablemodeling tools being-employed to. press th.-. layer into all of therecesseslof the-original? model. The above-layer.ofasbestos-fis then- Permitted to dryw qnhe aft which it is re "the, q

bees-wax, and gasolene, the latter rendering the molded article impervious, and extraordinarily hard.

In practicing the invention with respect to more complicated models, the process consists in pressing about the article, the repro duction of which is being made, a thin. layer of'plastic substance obtained by mixing raw asbestos pulp, kaolin, whiting, or plaster of paris with dissolved glue, flour paste, and.

linseed oil, all in such proportions as to yield a paste of about the consistency of dough; The above plastic 'layer is then backed by strips 2 of sheet asbestos, adhesively applied thereto. The above product is then permitted to dry, and when dry it is saturated withheated paraflin, oxid. of lead, and a suitable pigment by which it is rendered impervious, .washable," and of the desired color. The strips 2 of asbestos, as will be noted on reference to Fig. 2 of the drawings, serve toreinforce and rigidlfy the body of the reproduction after it becomes hardened. I

' The use of asbestos as heretofore described isessential to the production .of the desired results in the manufacture of composition of art models in accordance with the present ,invention. Asbestos, as is well known, af-

fords great, strength and toughness by reason of its fibrous nature, and at the same time, it is extremely light, answering the requlrements inthis respect. No method heretofore practiced, so far as is known, has resulted in producing articles of the nature of the resent invention combining strength, plasticity and lightness. Asbestos is also washable,

particularly advantageous because when it is combined with the stiffening materials hereinbefore described, it produces a pllable,

the corner edges and delicate projectionsof various molded articles are most exposed to damage in handling.- The stifl'ening or v hardening materials used not only facilitate the production of. a plastic article,yielding' non-combustible plastic body which takes iii the desired impression from the mold, but said materials are the only ones that have been discovered which prevent the composition from sticking in the molds.

Articles or reproductions made in accordance Withthis invention are of unlimited durability, and their lightness, consistency and lasting qualities render them highly advantageous for use in teaching or drawing, modeling, and the arts in general.

Having thus described the invention, what is claimed as new is:

1. The process of making reproductions of models as hereinbefore set forth, consisting in placing upon an original model a layer of asbestos in moistened pliable condition, shaping said layer-into the form of the original model by pressing the substance into the recesses of said mold by suitable tools, permitting the product to dry, and then eeaeos saturating the dried product with a compound including oxid of lead, gum, beeswax, and gasolene.

2. The process of making reproductions of models, figures, or the like, and consisting in molding a thin layer of plastic substance including raw asbestos pulp, kaolin, whiting, flour paste, and linseed oil, about the original model, backing said layer with strips of asbestos sheets adhesive 1y applied thereto, permitting the product to dry, and then rendering the product hard and impervious by a suitable compound.

In testimony whereof I afiix my signature in presence of two Witnesses.
